The problem w mob programming is that measured purely on a man-hour cost it sounds extremely stupid and expensive for a company. It has always sounded to me like a hare brained idea that a dev shop came up with to sell more man hours per feature delivered.
Depends - I have seen enough throw a mythical manmonth worth of developers at embarrassingly unparallelizable work and watch the tech debt pile up like it’s a 2007 mortgage bubble. And that code then trips people up day after day as more features are added.
